ABSTRACT:
A fuel pump for pumping fuel is provided in a sub-tank suspended in a fuel tank in order to reserve a fuel volume necessary for the fuel pump to be started on an inlet side of the fuel pump in the fuel tank. A fuel level holding member formed so as to rise upward on a suction opening side of the fuel pump reserves the fuel in space of the risen part. Thus, a structure for reserving the fuel volume pumped by the fuel pump in the fuel tank can be obtained with a simple construction.
